And the reason for this is? You just tell WHAT you are doing, not the WHY.

Looking at the patch which implements the uv4 wait function it uses the
thing as well. So for the casual reader there is no point.

The only reason i figured why you want to do that is to reduce the number
of arguments to the wait function, correct?

If yes, then spell it out. If no, please enlighten me.
